as ina siphon-bottles; Itfis apparent thatthe' emptying of the bottlec'anbe checked at any 5 q timeand the remaining portion of the con- 7 tents retained therein.

In a construction -ofIjstojpper heretofore de I visedhaving a tube.runninglengthwise of 1 the. cork and the valve at the lower-fend therewe of a bushing has beenproyided between such" tubeand'the corkfor'the entire length of the cork. 1 This construction was defective for sure for the reason that if there was any space between the tube and bushing the contents of the bottle upon the valve being opened would be forced through such space, or if the bushing was fitted so snugly upon the tube as to prevent the liquids being forced between such parts then the friction between such tube and bushing would be so great as to render the same inoperative. It will be seen that in my device there is no friction upon the tube 5 except for a short distance at the lower end thereof, the lower end of the cork 2 forming a packing around the tube 5 and at all times preventing a passage of the liquid above the end of such cork except through said tube. The circular ridge 7 upon the valve 6 presses or cuts slightly into the end of the cork 2, rendering the action of the valve more positive, a feature which is of more importance in bottles containing gaseous liquids.

The bottle is capable of being filled or refilled through the tube 5 by reversing the process.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. In a stopper for bottles, the combination, with such bottle, of an elastic cork, adapted to be securedin the neck of the bottie; a tube, extendinglengthwise of the cork, providing means of discharge for the contents of the bottle; a valve at the inner end of said tube adapted to prevent discharge of such contents when said valve is in contact with said cork; means for retaining such valve movably against said cork; and a wedgeshaped plug inserted centrally of the cork, and adapted to force such cork against the inner face of the neck of the bottle, and also prevent friction of such cork upon said tube for the greater part of the length of said cork; substantially as shown and set forth.

2. In a stopper for bottles the combination with such bottles of an elastic cork, adapted to be secured in the neck of the bottle; a tube extending lengthwise of the cork providing means of discharge for the contents of the bottle; a Valve at theinner end of said tube adapted to prevent discharge of such contents when said valve is in contact with said cork; means for retaining such valve movably against such cork; a wedge-shaped plug inserted centrally of the cork and adapted to force such cork against the inner face of the neck of the bottle, and also prevent friction of such cork upon said tube for the greater part of the length of said cork; and an annular recess in the inner face of the neck of such bottle substantially as described. In testimony whereof I aflix my signature in presence of two witnesses.
